'1"0 all whom if mog/ concer/4,:

Be it. known that l. Emmer MarnnwsoN, a citizen oi` the United btates, and resident of Buffalo. Erie county, State o'l New York, have invented certain new and useful improvements in Bumpers. of which the tollowing is a specification.

This invention relates to an improvement in bumpers and partici'llarly to the means 'for attaching; the bumper to the vehicle.

One object of this invention is to provide a bracket for attaching a bumper to a vehicle ot the type in which the trame has a protriulinzeY front end carrying the front springs 'as for example the Overland Four. This trame is made up of longitudinally extendingl open sided channel members.

Another object is to provide a bracket which can be quickly and rigidly bolted to the vehicle without the necessity oi'l boring any additional holes in and thus weakening the frame. p

.A further obj ect is to provide a bracket so formed that the shock received by the bumper is transmitted directly to the trame without putting any undue strain on the bracket holding: bolts.

Other objects will appear from a. con sideration ot the specification and the drawings forming a part thereof. and in which.

Figure 1 shows a plan View ot the trontend of a vehicle of the type mentioned above provided with a spring; bumper; Fig. 2 shows a side view ot the bracket secured in place; and Fig. 3 is a plan view ot the same.

ln vehicles of the Overland Four type it is impossible to mount a bumper in the usual manner upon the spring;l horns. By my invention the bumper is securely mounted.y and in addition use is made of the bolt holes already provided in the channel mem bers for other purposes thus avoiding the necessity and difficulty of boring additional holes.

Referring to the drawing, the reference numeral lb designates the front end ot a vehicle chassis having longitudinally extending side channel members 1l and projecting front spring plates 12, bolted to the inner sides of the members 11 and carrying the.

bumpers 15 above the front axle to take the shock in case the vehicle goes over a. severe bump. The numeral 16 indicates a part of the body which is carried by the chassis.

The spring bumper 17 extends in front oi lthe Chassis 10 and the wheels 18 as shown in Fig. 1 and is fastened to the channel members by brackets 19. Gnly one or" these brackets, the one on the left side, is illustrated but it will be understood that both are the sainev and are bolted to the members 11 in the. same manner. Each bracket 19 is bent at right angles to form a bottom plate 20, and a side plat-e 21, having bolt holes in the bottom plate and bolt hole 23 in the side plate. The. back of the side plate 21 is cut away to :lorm the shoulder 2l and the front is similarly cut away to 'form the shoulder 25. "When the bracket is mounted on the side member 11 the front end of the latter engages the shoulder 2l and 'thus determines the proper position ot the bracket. ln this position the holes 22 in the bottom plate coincide with the bolt holes ot the rubber bumper 157 while the hole 23 in the sigle plate coincides with the bolt holes ot the spring plate 12. The bracket is so bolted to the side member by bolts 26 pas ing through the holes 22 and 'the bumper bolt holes and b v a bolt 2T which passes through the bolt hole 23 and the spring plate bolt hole. The bolts 2 thus hold both the bracket 19 and the bumper l5 to the member 11 while the bolt 27 holds both the bracket and the spring plate to the same member. The bracket is thus quicklyv and securely fastened to the channel member without weakening it. by making additional holes therein.

The end ot the spring bumper 1T is bolted to the bracket 19 and is seated against the shoulder 25. Any shock received by the spring bumper is transmitted through the shoulders 25 and 24 directly to the side mem bers and the danger of shearing oil" the bolts 2G and 27 is avoided. 1While the bolt holes 22 and 23 are shown round theymay be oval it desired, to allow for any variance in the position ofthe rubber bumper and spring vplate holes.

While only one embodiment of this invention has been shown and described, it will be obvious that other embodiments can be made without departing from the spirit and scope W bumper is scribed throughout the specification as attached to the front end of the Vehicle it is equall adapted to be attached to the rear end ot a vehicle such as the Overland Four in which the rear end also protrudes to support the rear springs.

Having thus set forth my invention, what I claim and desire to protect by Letters Patent is:

bracket for attaching a bumper to a vehicle having longitudinally extending channel members, consisting of a right angle plate seated in the channel of one of said members and secured thereto by bolts passing through bolt holes already provided in said members for other purposes.

2. Means for attaching a spring plate bumper to a vehicle having longitudinally extending channel members, consisting of a bracket cut away on both sides to Vform Vertical shoulders, the spring plate of the` bumper being fastened to the bracket with its end against one shoulder, and the bracket being secured to one of the said channel members with the front end of the member engaging the other shoulder A 3. ln a vehicle having longitudinally extending channel members, a rubber bumper block on the under side of each of said members, a spring plate on the side of said member, a bracket, a spring bumper fastenedv to said bracket, and means securing said bracket, block, and plate to said chanF nel member.

4. A bracket for attaching a bumper to a vehicle having longitudinally extending' channeled side members, comprising a right angle plate seated in and fastened to the channel of one of said members.

In testimony whereof, l atlix my signature.
